outwards. The fingers are nearly as long as the palm, elon- 
gate, and becoming more narrowed or acute at the ends ; tney 
are excavate, and have no hiatus in either sex, and are mi- 
nutely serrate on their outer opposable edges. The immobile 
finger terminates in two strong, hooked teeth, with one more 
or less rudimentary on each side. The mobile finger has one 
hooked tooth, with a rudiment on each side. 
The following three pairs of legs are very spmy and very 
setose. The dactyli are strong, with horny, curved claws and 
marginal spines. 
In both species the telson of the male has on each side 
above the middle a group of strong, corneous bristles ; these 
on stronger magnification appear to be hollow, and have their 
tips split, and in spirit specimens have a shiny appearance 
and golden colour. G. austral lensis varies in colour, speci- 
mens from shallow water are greenish or bluish, those from 
20-30 fms. are deep red. The present species has a remark- 
able colouration. The carapace is white in the middle, and 
towards each side is a band of colour, in which violet, orange, 
and brown are seen. The sternal surface is orange. The 
chelipeds are white, with red spots, the fingers are deep red. 
Tiie legs are banded with violet, orange, and white. The an- 
tennal flagella are red. 
Although the differences between these two species are 
small, they appear constant ; a moderate series of specimens 
having been observed with no sign of intermediacy. In prac- 
tice they are not difficult to separate. 
Through the kindness of the Director of the Australian 
Museum, I have been able to compare this species with G. 
aculeata, Haswell, and note the following differences: — G. 
aculeata is much less setose and spinose on all parts, its ros- 
trum is nearly smooth, and its terminal spine is much slen- 
derer and lanceolate. The joints of the chelipeds are much 
less robust, the carpi being longer. The fingers are notably 
longer than the palm. 
From G. magnifica, Haswell, it differs in the coarse ^id 
harsh hairs of the carapace. In the striae of the gastric region 
being broken up into arcuate lobes. In the setose, rostrum, 
eye peduncles, and limbs. The colour markings are also 
different.
